Objective:(1) Discuss the value of Advantage Windows 3.1 (AW 3.1) imaging software for anatomical study of nasofrontal region. 探讨Advantage Windows 3.;1(AW 3
They are also widest at the nasofrontal suture, narrowest at the nasofrontal angle, and tend to widen again inferior to the radix before narrowing near their inferior margin. 最宽部分在鼻额相接处，鼻额角处最窄，从鼻根重新变宽，至接近下缘处再次变窄。
The adjacent structures of the ostia differ from each other by the different location of the ostium.The clinical significance of the ostium and the nasofrontal duct were discussed. 认为，开口于不同部位的额窦窦口周围结构不同，对研究额窦的生理、病理，以及提高鼻窦内窥镜检查和额窦开放手术具有重要的参考和指导意义。
